Abstract

1. A method for making a cone, in the course of which a blank produced from a foldable, flexible flat material such as paper metal foil or a similar material is wound around a conical mandrel, wherein the whole of the conical cone is simultaneously formed between an inner and an outer forming part (14, 15) and the inside of the cone is at least at certain points given elastic support during the forming process, as a result of which folds (4, 7, 10) extending essentially in a longitudinal direction are formed in at least one tapered section of the cone.

Description

Die Erfindung bezieht sich auf eine Spitztüte aus hauptsächlich kegelig aufgerolltem falt- und biegbarem Flachmaterial, wie Papier, Metallfolie usw. Solche Spitztüten werden allgemein zum Verpacken von kegeligen Eiswaffeln verwendet zum mechanischen, thermischen und hygienischen Schutz derselben und zum Tragen von Werbeaufschriften und Bildern.The invention relates to a lace bag made mainly of conically rolled, foldable and bendable flat material, such as paper, metal foil, etc. Such lace bags are generally used for packaging cone-shaped ice cream cones, for mechanical, thermal and hygienic protection thereof and for carrying advertising labels and pictures.

Aufgabe der Erfindung ist eine Vergrösserung des thermischen Schutzes auf möglichst wirtschaftliche Weise und unter Beibehaltung der übrigen Eigenschaften der herkömmlichen Spitztüte zu verwirklichen. Eine weitere Aufgabe ist eine Spitztüte für eine kegelige Eiswaffel mit erweitetem Mündungsbereich herzustellen. Ausserdem hat die Erfindung zur Aufgabe, die mechanische Festigkeit der Spitztüte wo möglich zu vergrössern. Des Weiteren hat die Erfindung zur Aufgabe ein Verfahren zur Herstellung solcher Spitztüten und eine Vorrichtung zur Durchführung dieses Verfahrens zur Verfügung zu stellen.The object of the invention is to increase the thermal protection in the most economical manner and to maintain the other properties of the conventional lace bag. Another task is to produce a cone for a conical ice cream cone with an enlarged mouth area. In addition, the invention has the task of mechanical To increase the firmness of the lace bag where possible. Furthermore, the object of the invention is to provide a method for producing such cones and an apparatus for carrying out this method.

Zu diesem Zweck bietet die Erfindung eine Spitztüte der anfangs beschriebenen Gattung, die wenigstens einen bezüglich des Mündungsbereichs verjüngten Mittelbereich mit hauptsächlich in Längsrichtung verlaufenden Falten aufweist. Vorzugsweise bilden die Falten rippenartige, auswärts gerichtete Vorsprünge bis zum unteren Bereich der Tüte. Es ist jedoch auch möglich, die Falten als Kellerfalten zu bilden, wodurch eine ziemlich glatte Aussenoberfläche beibehalten bleibt trotz Vergrösserung der thermischen Isolation und Stegerung der Festigkeit.For this purpose, the invention provides a pointed cone of the type described at the beginning, which has at least one central region tapered with respect to the mouth region with folds running mainly in the longitudinal direction. The folds preferably form rib-like, outward projections up to the lower region of the bag. However, it is also possible to form the folds as basement folds, as a result of which a fairly smooth outer surface is retained despite the increase in thermal insulation and an increase in strength.

In einer einfach herzustellenden Ausführungsform sind die Falten abwechselnd ein- und auswärts gerichtet und bilden eine Zickzackwandung.In an embodiment that is easy to produce, the folds are alternately directed inwards and outwards and form a zigzag wall.

Eine zum Verpacken von kegeligen Eiswaffeln mit erweitetem Mündungsbereich, z.B. in Form einer Halbkugel oder eines Kegelstumpfes mit von derjenigen des unteren Bereiches abweichender Kegelform geeignete Ausführungsform weist vorzugsweise durch einen Verbindungsbereich verbundene Teile unterschiedlicher Kegelform auf. Dabei kann der obere Mündungsbereich der Spitztüte entweder kegelig, was billiger herstellbar ist, oder regelmässig vieleckig sein, was eine etwas grössere Festigkeit ergibt.One for packaging conical ice cream cones with an enlarged mouth area, e.g. in the form of a hemisphere or a truncated cone with a conical shape which is suitable from that of the lower region, preferably has parts of different conical shape connected by a connecting region. The upper mouth region of the pointed cone can either be conical, which is cheaper to manufacture, or can be regularly polygonal, which results in a somewhat greater strength.

Beim Verfahren zur Herstellung einer erfindungsgemässen Spitztüte wird vorzugsweise auf herkömmliche Weise ein Zuschnitt aus Flachmaterial um einen kegeligen Dorn gewickelt und in Abweichung vom bekannten Verfahren wird dann die erhaltene kegelige Spitztüte zwischen einem Innen- und einem Aussenformteil am ganzen Umfang zur gleichen Zeit verformt, wobei die Innenwandung der Spitztüte wenigstens stellenweise nachgiebig unterstützt wird. In dieser Weise kann die ursprüngliche Spitztüte klemmend auf den Innenformteil geschoben werden, wobei die Fältelung sich form- und stellengerecht ergeben wird. Dieses Verfahren bietet den Vorteil, dass es schnell vor sich geht, gleichmässig über den Umfang verteilte Falten ergibt und eine gegenseitige Ausrichtung der Dekoration auf der Spitztüte und der Falten in einfacher Weise ermöglicht.In the method for producing a lace bag according to the invention, a blank of flat material is preferably wrapped around a conical mandrel in a conventional manner and, in deviation from the known method, the conical lace bag obtained is deformed between an inner and an outer molded part over the entire circumference at the same time, the The inner wall of the lace bag is at least partially supported in a flexible manner becomes. In this way, the original lace bag can be pushed onto the inner molded part by clamping, the pleating being obtained in accordance with the shape and position. The advantage of this method is that it is quick, results in folds evenly distributed over the circumference and enables the decoration on the lace bag and the folds to be aligned with one another in a simple manner.

Die für dieses Verfahren verwendbaren radial beweglichen Innenformteilabschnitte können sowohl auswärts federbelastet als auch bevorzugt gesteuert in radialer Richtung ein- und ausbewegt werden, damit während der Verformung keine allzugrosse Reibung zwischen dem Aussenformteil und der Spitztüte auftritt.The radially movable inner molded part sections that can be used for this process can be spring-loaded outwards and preferably moved in and out in a controlled manner in the radial direction, so that no excessive friction occurs between the outer molded part and the cone during the deformation.

Zum Schluss bezieht die Erfindung sich auf eine Vorrichtung zur Herstellung einer erfindungsgemässen Spitztüte, die mit in- und auseinander beweglichen Innen- und Aussenformteilen, von denen wenigstens in ineinander bewegter Stellung die Aussen- bzw. Innenoberfläche zwischen einander die Form der verformten Tüte beschreiben, versehen ist, wobei erfindungsgemäss wenigstens der Innenformteil mit radial beweglichen, sich hauptsächlich in Richtung der Erzeugenden erstreckenden und im Bereich der Kegelspitze des Formteils drehbar unterstützten Formteilabschnitten versehen ist.Finally, the invention relates to a device for producing a lace bag according to the invention, which is provided with inner and outer molded parts that can be moved in and out of each other, of which at least in the position moved into one another the outer or inner surface between them describe the shape of the deformed bag According to the invention, at least the inner molded part is provided with radially movable molded part sections which extend mainly in the direction of the generatrix and are rotatably supported in the region of the cone tip of the molded part.

Fig. 1 und 2 zeigen eine erfindungsgemässe Spitztüte in einer bevorzugten Ausführungsform in Seitenansicht bzw. in Quer-. schnitt. Zwei Wandbereiche 2,6 verschiedener Kegelform sind durch einen Verbindungsbereich 1 verbunden. Der Mündungsbereich 2 weist dieselbe Kegelform wie die ursprüngliche, mit unterbrochenen Linien 3 angegebene Spitztüte, von der ausgegangen wird, auf. Durch Falten 4 in Richtung der Erzeugenden werden auswärts gerichtete Vorsprünge 5 oder Rippen gebildet, die eine Verfestigung der Spitztüte mit sich bringen und zudem beim Festhalten zum Abstandhalten dienen. Durch diese Fältelung ist die Spitztüte im mittleren und unteren Bereich verjüngt, so dass entsprechend geformte Eiswaffeln darin gestützt werden können.1 and 2 show a lace bag according to the invention in a preferred embodiment in side view and in transverse. cut. Two wall areas 2, 6 of different cone shape are connected by a connecting area 1. The mouth region 2 has the same conical shape as the original pointed cone, indicated by broken lines 3, from which it is assumed. By folding 4 in the direction of the generatrix outward projections 5 or ribs are formed, which bring about a solidification of the piping bag and also serve to keep away from holding. Due to this pleating, the cone is tapered in the middle and lower area, so that appropriately shaped ice cream cones can be supported in it.

In Fig. 3 ist dargestellt, wie die Falten derart geordnet sind, dass Kellerfalten 7 im mittleren und unteren Bereich der Spitztüte gebildet sind. Im übrigen entspricht diese Ausführungsform der in Fig. 1 dargestellten.FIG. 3 shows how the folds are arranged in such a way that basement folds 7 are formed in the middle and lower region of the lace bag. Otherwise, this embodiment corresponds to that shown in FIG. 1.

In Fig. 1 ist der Mündungsbereich abgestumpft kegelig gezeichnet, kann jedoch ebensogut regelmässig abgestumpft pyramidal sein.In Fig. 1 the mouth region is bluntly tapered, but can equally well be blunted pyramidal regularly.

In der Ausführungsform nach Fig. 4 sind nur im mittleren Bereich, wo die Spitztüte normalerweise festgehalten wird, gewendelte zickzackförmige Falten 10 angeordnet, während die Spitze 11 und der Mündungsbereich 12 noch die ursprüngliche Kegelform aufweisem. Mit "gewendelt" wird in diesem Zusammenhang eine von der Erzeugenden abweichende Konfiguration der Falten gemeint.In the embodiment according to FIG. 4, coiled zigzag folds 10 are arranged only in the central area, where the lace bag is normally held, while the tip 11 and the mouth area 12 still have the original conical shape. In this context, "coiled" means a configuration of the folds that differs from the generator.

Eine zur Herstellung der Spitztüte nach Fig. 1 geeignete Vorrichtung ist in den Fig. 5ab und 6ab dargestellt. Nach diesen Figuren weist die Vorrichtung einen Innen- und einen Aussenformteil 14 bzw. 15 auf. Der Aussenformteil 15 weist eine kegelige Höhle 16, dem unteren Bereich 6 der verformten Spitztüte entsprechend, und eine durch einen stufenförmigen Verbindungsbereich 18 damit verbundene kegelstumpfförmige Höhle 17, dem oberen Bereich oder Mündungsbereich 2 der Spitztüte entsprechend, auf.A device suitable for producing the lace bag according to FIG. 1 is shown in FIGS. 5ab and 6ab. According to these figures, the device has an inner and an outer molded part 14 and 15, respectively. The outer molded part 15 has a conical cavity 16, corresponding to the lower region 6 of the deformed pointed cone, and a frustoconical cavity 17 connected to it by a step-shaped connecting region 18, corresponding to the upper region or mouth region 2 of the pointed cone.

In der Innenwand der Höhle 16 sind in Richtung der Erzeugenden Nuten 19 vorgesehen, in welche in entsprechenden Schlitzen 21 im Innenformteil 14 angeordnete Stege 20 radial auswärts mit Spiel einfahrbar sind. Die Stege 20 sind je ah der Unterseite bei 23 schwenkbar im Innenformteil 14 gelagert und sind durch einen axial beweglichen Steuerungskopf zwischen einem Innen-und einem Aussenstand (Fig. 5b links bzw. rechts) verstellbar. Zur Verjüngung einer Spitztüte wird diese auf den Innenformteil 14 mit ausbewegten Stegen 20 aufgesteckt und zusammen mit demselben in den Aussenformteil 15 hineingefahren. Dabei wird die Spitztüte im mittleren und unteren Bereich allmählich verjüngt, während zwischen den allmählich einbewegten Stegen 20 und den Nuten 19 die rippenartigen Vorsprünge 5 gebildet werden. Nach Ausfahren des Innenformteils 14 wird die fertige Spitztüte mit einem auf deren Spitze angreifenden Ausstosser 24 ausgestossen.In the inner wall of the cavity 16, grooves 19 are provided in the direction of the generating grooves, into which webs 20 arranged in corresponding slots 21 in the inner molded part 14 can be inserted radially outwards with play. The webs 20 are each pivotally mounted on the underside at 23 in the inner molded part 14 and can be adjusted between an inner and an outer position (FIG. 5b left or right) by an axially movable control head. To taper a pointed cone, this is placed on the inner molded part 14 with the webs 20 moved out and moved together with the same into the outer molded part 15. The pointed cone is gradually tapered in the middle and lower region, while the rib-like projections 5 are formed between the gradually moved-in webs 20 and the grooves 19. After the inner molded part 14 has been extended, the finished pointed bag is ejected with an ejector 24 acting on its tip.
